Some time ago a friend of mine, who is a co - organizer of Geecon
(thanks Ags!) asked me about giving a
talk about "how to maintain applications on production".

So I thought that instead of some generic talk I'll work on a presentation
where I would describe
in details how we worked on reliability matters @Codewise.
And the story should be interesting to people, as our company is well known for
running low - latency, high traffic systems (400k requests/s total).

I run this presentation three times, second even as a keynote during
DevopsDays Poznań event.

The interesting part is originally this presentation was meant to tell a story
of a no-ops company running own Cassandra clusters, however after Geecon
edition I changed it a bit and removed Cassandra - related slides, as it turned
out that people are very interested in reliability subjects but in a generic
approach (not focused only on one service).
